TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidet power saving control method, and more particularly, to optimize power saving by sensing illuminance using an illuminance sensor and controlling power saving according to the sensed illuminance level. The present invention relates to a bidet power saving control method.
[0002]
[Prior art]
In general, bidets have a function to automatically spray water when the user presses the wash button after use, and to wash the stool area. It is widely known as a device provided with a drying function for drying the paper and a power saving function for saving power when not in use.
[0003]
FIG. 1 is a perspective view showing an installation state of a general bidet that performs the above-described function. The bidet is provided on a toilet bowl 10 and has an operation panel 21 formed on one side of a bidet body 20. By the operation, hot water inside is sprayed through the nozzle 27 to automatically perform the anal cleaning and the local cleaning, and after the cleaning, the operation panel 21 is operated to generate hot air and dry automatically.
[0004]
In addition, a sheet 22 on which a user lays and sits in front of the bidet body 20 is rotatably provided, and a cover 23 for accommodating the sheet 22 is provided at an upper end of the bidet body 20 so as to be rotatable.
[0005]
In the above, anal cleaning refers to cleaning the anus without using tissue with cleaning water injected through the nozzle after stool, and local cleaning (or bidet cleaning) automatically cleans the local area with warm water. To do.
[0006]
FIG. 2 is a block diagram showing a configuration of a conventional bidet power saving device. Here, reference numeral 21 indicates an operation panel, reference numeral 30 indicates a water temperature sensor for detecting a water temperature in the washing water storage tank, and reference numeral 40 is mounted inside the sheet 22 and detects the temperature of the sheet. 3 shows a temperature sensor.
[0007]
Reference numeral 50 denotes a function signal applied through the operation panel 21 to control the operation of the entire apparatus so as to correspond to the function signal. The water temperature and the sheet temperature detected by the water temperature sensor 30 and the temperature sensor 40, respectively. 1 shows a control unit for controlling the driving of the heater and the heating wire.
[0008]
Reference numeral 60 denotes a heater driving unit 60 that drives the heater 70 in accordance with a heater driving control signal output from the control unit 50, and reference numeral 80 denotes a heating wire 90 according to the heating line driving control signal output from the control unit 50. Shows the hot-wire driving unit 80 that operates the.
[0009]
The conventional bidet power saving device configured as described above searches the control unit 50 for a function signal output from the operation panel 21, and as a result of the search, the water temperature output from the water temperature sensor 30 if the search is in use. The driving of the heater 70 is controlled by comparing the temperature with the temperature of the hot water selected by the user.
[0010]
For example, when the hot water temperature selected by the user is lower than the water temperature detected by the water temperature sensor 30, the heater driving unit 60 is operated to drive the heater 70. Here, when the heater 70 is driven, it generates heat and raises the temperature of the washing water. Of course, if the temperature of the hot water selected by the user is higher than the water temperature detected by the water temperature sensor 30, the heater driving unit 60 is turned off.
[0011]
Similarly, the controller compares the toilet seat temperature selected by the user with the sheet temperature detected by the temperature sensor 40, and controls the operation of the hot-wire driving unit 80 according to the magnitude of the comparison.
[0012]
On the other hand, when not in use, the control unit 50 unconditionally enters the power saving mode. In the power saving mode, the toilet seat temperature is set to be 5 ° C. lower than the previously selected warm water temperature, and at the same time, the toilet seat temperature is set to 5 ° C. lower than the previously selected toilet seat temperature. And a power saving function is performed by a method for controlling the power saving function.
[0013]
FIG. 3 is a flowchart showing a conventional bidet power saving control method. As shown here, a step S11 of confirming whether or not use is possible, a step S12 of operating in a normal mode if the result of the confirmation indicates that the apparatus is in use, and entering a power saving mode if the result of the confirmation indicates that the apparatus is not in use. Step S13, resetting the hot water and toilet seat temperature in a state where the power saving mode has been entered, step S15 of detecting the water temperature after resetting the hot water temperature, and resetting the detected water temperature and the reset hot water. Comparing the temperature with the temperature, operating the heater if the detected water temperature is lower than the reset hot water temperature, and turning off the heater if the detected water temperature is higher than the reset temperature. S18, after resetting the toilet seat temperature, a step S19 of detecting the toilet seat temperature, a step S20 of comparing the detected toilet seat temperature with the reset toilet seat temperature, A step S21 if the toilet seat temperature out is higher than the temperature of the resetting of blocking heat rays supply power, when the toilet seat the detected temperature is lower than the toilet seat temperatures above reconfiguration is in a stage S22 for driving the heat rays.
[0014]
In the conventional power saving control method for a bidet performed in this way, first, in step S11, it is determined whether the apparatus is in use or not in use (it can be determined using a seat switch). If it is determined that the device is in use, the process proceeds to step S12, and the device operates in the normal mode.
[0015]
On the other hand, if it is determined that the device is not in use as a result of the above-described confirmation, the process moves to S13 and enters the power saving mode. Thereafter, the process moves to step S14, and the hot water and toilet seat temperature are reset. Here, the hot water and toilet seat temperature are reset by subtracting 5 ° C. from the previous temperature level and resetting the hot water temperature and toilet seat temperature.
[0016]
Then, at the time of hot water control, the process proceeds to step S15 to detect the temperature of the washing water through the water temperature sensor 30, and compares the water temperature detected at step S16 with the reset temperature. As a result of the comparison, if the detected water temperature is lower than the reset temperature, the process proceeds to step S17 to drive the heater. On the other hand, if the detected water temperature is equal to or higher than the reset temperature, the process proceeds to step S18 to turn off the heater.
[0017]
Next, the process of toilet seat temperature control will be described as follows. In step S19, the toilet seat temperature is detected using the temperature sensor 40. Then, in step S20, the detected toilet seat temperature is compared with the reset temperature. As a result of the comparison, if the detected toilet seat temperature is the same as or higher than the reset temperature, the process proceeds to step S21 to cut off the power of the hot wire. On the other hand, if the detected toilet seat temperature is lower than the reset temperature, the process moves to step S22 to supply the driving power to the heating wire.
[0018]
[Means for Solving the Problems]
However, in the conventional power saving control method of a bidet, when not used, the temperature is reset by 5 ° C. below the previously set temperature, and then the system enters the power saving mode. Even in the middle of the night (for example, from 11:00 to 5:00 in the morning), power is supplied to the heater and the heating wire to maintain a constant temperature level, which causes various problems such as waste of power.
[0019]
Accordingly, the present invention has been proposed to solve various problems caused by the conventional bidet power saving control method as described above, and an object of the present invention is to detect illuminance using an illuminance sensor. Another object of the present invention is to provide a bidet power saving control method that controls power saving in accordance with the sensed illuminance level so that optimal power saving is performed.
[0020]
The bidet power saving control method according to the present invention for achieving the above-mentioned object is as follows.In the bidet power saving control method, whether or not the bidet is used is checked. Performing a first step of entering a power saving mode if it is determined that the apparatus is not in use; a second step of detecting surrounding illuminance using an illuminance sensor after entering the power saving mode; Comparing the value with a preset minimum set value to determine whether or not it is midnight, and if the sensed illuminance value is lower than the minimum set value, power saving is performed by an operation of turning off a heater and a heating wire. And if the sensed illuminance value is greater than the minimum set value, a fourth step of comparing the sensed illuminance value with a preset maximum set value to determine whether lighting is possible or not, and If the temperature value is lower than the maximum set value, a fifth step of setting a predetermined power saving temperature, controlling the driving of the heater and the heating wire to correspond to the set power saving temperature, and performing power saving, When the illuminance value is larger than the maximum set value, it is determined that the lighting is on, the power saving is canceled during a predetermined time, a normal temperature is set, and the driving of the heater and the heating wire is controlled in the sixth step. Features.
[0021]
In the above, the fifth step includes: setting the power saving temperature by setting the temperature of the hot water to 30 ° C. and the toilet seat temperature to 30 ° C. when the sensed illuminance value is lower than the maximum set value; Detecting, and comparing the detected water temperature with the set power saving temperature (30 ° C.). If the detected water temperature is lower than the set power saving temperature, the heater is driven, and the detected water temperature becomes A step of turning off the heater when the temperature is higher than the set power saving temperature; a step of detecting the toilet seat temperature at the time of toilet seat temperature control; and a step of comparing the detected toilet seat temperature with the set power saving temperature (30 ° C.). When the detected toilet seat temperature is lower than the set power saving temperature, power is supplied to the hot wire to drive the hot wire, and when the detected toilet seat temperature is higher than the set power saving temperature, the hot wire drive is performed. Made by the step of turning off the heat rays by blocking source.
[0022]
In the above, in the sixth step, when the sensed illuminance value is higher than the maximum set value, the power saving is canceled for a predetermined time (15 minutes), and the hot water temperature is set to 40 ° C. and the toilet seat temperature is set to 42 ° C. Setting the normal water temperature, controlling the hot water temperature, detecting the water temperature, comparing the detected water temperature with the set hot water temperature (40 ° C.), and setting the detected water temperature to the set hot water temperature. When the temperature is lower than the temperature, the heater is driven, and when the detected water temperature is higher than the set hot water temperature, the heater is turned off; when the temperature of the toilet seat is controlled, the temperature of the toilet seat is detected; And comparing the set toilet seat temperature (42 ° C.) with the set toilet seat temperature (42 ° C.), and when the detected toilet seat temperature is lower than the set toilet seat temperature, supplying power to the hot wire to drive the hot wire, Higher than the toilet seat temperature as the setting is at the stage of turning off the heat rays cut off heat rays driving power.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention based on the above-described technical concept will be described in detail with reference to the accompanying drawings.
[0024]
FIG. 4 is a block diagram showing a configuration of a bidet power saving control device to which the present invention is applied. Here, reference numeral 21 denotes an operation panel provided with a hot water temperature key, a toilet seat temperature key, a stop key, and the like, reference numeral 30 denotes a water temperature sensor for detecting a water temperature in the washing water storage tank, and reference numeral 40 denotes a water temperature sensor. A temperature sensor attached to the inside of the sheet 22 for detecting the temperature of the sheet (toilet seat temperature) is shown, and reference numeral 100 indicates an illuminance sensor for detecting the surrounding illuminance.
[0025]
Further, reference numeral 50 indicates a function signal applied through the operation panel 21 and controls the operation of the entire apparatus so as to correspond to the function signal, and according to the water temperature and the toilet seat temperature detected by the water temperature sensor 30 and the temperature sensor 40, respectively. A control unit that controls driving of a heater and a heating wire and controls a power saving operation in a power saving mode according to an illuminance value sensed by the illuminance sensor 100 is shown.
[0026]
Reference numeral 60 denotes a heater driving unit 60 that drives the heater 70 according to a heater driving control signal output from the control unit 50, and reference numeral 80 denotes a heating wire 90 according to a heating wire driving control signal output from the control unit 50. Shows the hot-wire driving unit 80 that operates the.
[0027]
In the bidet device to which the present invention thus configured is applied, the control unit 50 searches for a function signal output from the operation panel 21, and as a result of the search, outputs a signal from the water temperature sensor 30 if the signal is in use. The driving of the heater 70 is controlled by comparing the water temperature with the hot water temperature selected by the user.
[0028]
For example, when the hot water temperature selected by the user is lower than the water temperature detected by the water temperature sensor 30, the heater driving unit 60 is operated to drive the heater 70. Here, when the heater 70 is driven, it generates heat and raises the temperature of the washing water.
[0029]
Of course, when the hot water temperature selected by the user is higher than the water temperature detected by the water temperature sensor 30, the heater driving unit 60 is turned off. Similarly, the toilet seat temperature selected by the user is compared with the sheet temperature detected by the temperature sensor 40, and the operation of the hot-wire drive unit 80 is controlled according to the magnitude of the comparison.
[0030]
On the other hand, when not in use, the control unit 50 enters the power saving mode, and controls the power saving mode according to the illuminance value detected by the illuminance sensor 100.
[0031]
For example, if the sensed illuminance value is lower than a minimum set value for determining whether the detected illuminance value is midnight (11 to 5 o'clock in the morning), it is determined to be midnight and the heater is unconditionally turned off, The power saving operation is controlled by a method of shutting off the supply power of the power supply.
[0032]
Also, if the sensed illuminance value is lower than the maximum set value set to determine whether or not to light, that is, if the sensed illuminance value is equal to or more than the minimum set value and equal to or less than the maximum set value, the change from early morning to morning As described above, the power saving operation is controlled by setting a specific power saving temperature (for example, a hot water temperature of 30 ° C. and a toilet seat temperature of 30 ° C.).
[0033]
When the sensed illuminance value is higher than the maximum set value, it is determined that the light is turned on, and the power saving is unconditionally canceled for a predetermined time (about 15 minutes), and the hot water temperature is reduced to 40 ° C. The operation of the heater and the heating wire is controlled by setting the toilet seat temperature to 42 ° C.
[0034]
5A and 5B are flowcharts showing a bidet power saving control method according to the present invention. As shown here, steps S101 to S103 for checking whether or not use is possible, operating in a normal mode when determined to be in use, and entering a power saving mode when determined to be not in use, After entering the power saving mode, the surrounding illuminance is detected using an illuminance sensor in step S104, and the detected ambient illuminance value is compared with a preset minimum setting value for determining whether or not it is midnight. If the sensed illuminance value is lower than the minimum set value, power saving operations are performed by turning off the heater and the heating wire, and if the sensed illuminance value is greater than the minimum set value, the sensing is performed. Comparing the illuminance value with a preset maximum set value in order to determine whether or not to turn on the light; and a step S107 when the sensed illuminance value is lower than the maximum set value. Setting the electric power temperature, controlling the driving of the heater and the heating wire so as to correspond to the set electric power saving temperature to perform power saving, and lighting if the sensed illuminance value is larger than the maximum set value. Then, power saving is canceled for a predetermined time, and a normal temperature is set to control the driving of the heater and the heating wire, and there are steps S117 to S126.
[0035]
In the above, steps S108 to S116 include, when the sensed illuminance value is lower than the maximum set value, setting the hot water temperature to 30 ° C. and setting the toilet seat temperature to 30 ° C. to set the power saving temperature, and A step S109 of detecting a water temperature, a step S110 of comparing the detected water temperature with the set power saving temperature (30 ° C.), and if the detected water temperature is lower than the set power saving temperature, a heater is driven to perform the detection. If the detected water temperature is higher than the set power saving temperature, steps S111 and S112 for turning off the heater, a step S113 for detecting the toilet seat temperature during the toilet seat temperature control, and the detected toilet seat temperature and the set power saving temperature (30 C), and if the detected toilet seat temperature is lower than the set power saving temperature, power is supplied to the heating wire to drive the heating wire. It is allowed, if the toilet seat the detected temperature is higher than the power-saving temperature and the setting is at the stage S115 and S116 to turn off the heat rays cut off heat rays driving power.
[0036]
In the above, step S117 includes a step S117 of canceling power saving for a predetermined time (15 minutes) when the sensed illuminance value is higher than the maximum set value, and setting the hot water temperature to 40 ° C and the toilet seat temperature to 42 ° C. Step S118 of setting a normal temperature by controlling the temperature of the hot water, Step S119 of detecting the water temperature during the hot water control, Step S120 of comparing the detected water temperature with the set hot water temperature (40 ° C.), and If the temperature is lower than the set hot water temperature, the heater is driven, and if the detected water temperature is higher than the set hot water temperature, the heater is turned off. Comparing the detected toilet seat temperature with the set toilet seat temperature (42 ° C.), and determining the detected toilet seat temperature as the set toilet seat. If the temperature is lower than the temperature, the power is supplied to the heating wire to drive the heating wire, and if the detected toilet seat temperature is higher than the set toilet seat temperature, the heating wire driving power supply is shut off to turn off the heating wire. .
[0037]
The method for controlling power saving of a bidet according to the present invention will now be described in detail with reference to the accompanying drawings. First, in step S101, the use of the seat is checked using a seating switch. If it is determined that the seat is in use, the process proceeds to step S102 to operate in the normal mode. Here, the normal mode is a general bidet operation mode, and a detailed description thereof will be omitted.
[0038]
As a result of the check, if it is determined that the device is not in use, the process proceeds to step S103 and the device enters the power saving mode. After entering the power saving mode, in step S104, the illuminance around the bidet is detected using the illuminance sensor 100. In step S105, the detected illuminance value around the bidet and whether it is midnight or not is determined. Is compared with a preset minimum set value.
[0039]
Here, the preset minimum set value is a reference value for determining whether or not it is midnight, and it can be defined that the normal midnight is usually from 11:00 pm to 5:00 in the morning. The time period is bedtime, and almost no bidet is used. Therefore, in that case, it can be said that turning off both the heater and the heating wire can provide optimal power saving.
[0040]
If the result of the comparison indicates that the detected illuminance value is lower than the minimum set value, the operation proceeds to step S106 to turn off the heater and the heating wire to save power.
[0041]
On the other hand, if the sensed illuminance value is greater than the minimum set value, the process proceeds to step S107, where the sensed illuminance value is compared with a preset maximum set value to determine whether or not to light. Here, the maximum set value is a reference value set to determine a case where the video is turned on to use the bidet at midnight.
[0042]
If the detected illuminance value is lower than the maximum set value, the process proceeds to step S108 to set a predetermined power saving temperature, and controls the driving of the heater and the heating wire to correspond to the set power saving temperature to save power. Will do it.
[0043]
That is, when the sensed illuminance value is lower than the maximum set value as in step S108, the power saving temperature is set by setting the hot water temperature to 30 ° C and the toilet seat temperature to 30 ° C. In step S109, the temperature of the washing water (water temperature) is detected using the water temperature sensor 30 during the hot water control. In step S110, the detected water temperature and the set power saving temperature (hot water temperature, 30 ° C).
[0044]
As a result of the comparison, if the detected water temperature is lower than the set power saving temperature, the process proceeds to step S111 to drive the heater, and in contrast thereto, the detected water temperature is higher than the set power saving temperature. In this case, the process proceeds to step S112 to turn off the heater.
[0045]
Next, at the time of controlling the toilet seat temperature, the process moves to step S113 to detect the toilet seat temperature using the temperature sensor 40. In step S114, the detected toilet seat temperature and the set power saving temperature (toilet seat detection temperature, 30 ° C.).
[0046]
As a result of the comparison, if the detected toilet seat temperature is lower than the set power saving temperature, the process proceeds to step S116 to supply power to the heating wire and drive the heating wire. If the temperature is higher than the set power saving temperature, the process proceeds to step S115 to shut off the hot wire driving power supply and turn off the hot wire.
[0047]
That is, when the illuminance detected by the illuminance sensor 100 is larger than the minimum set value and smaller than the maximum set value, it means that the brightness gradually increases toward the morning. In particular, since it is a point of time from the early morning to the morning, in this case, if the temperature of the washing water and the toilet seat is maintained to some extent, the use of the morning bidet makes it impossible to feel cold air. Therefore, in this case, after setting an appropriate power saving temperature, the heater and the heating wire are controlled to save power.
[0048]
Also, when the sensed illuminance value is greater than the maximum set value, it is determined that the lighting is on, power saving is canceled for a predetermined time, a normal temperature is set, and the driving of the heater and the heating wire is controlled. Become.
[0049]
That is, in step S117, if the sensed illuminance value is higher than the maximum set value, the power saving is canceled for a predetermined time (about 15 minutes). Then, in step S118, the normal temperature is set by setting the hot water temperature to 40 ° C. and the toilet seat temperature to 42 ° C.
[0050]
Next, at the time of hot water control, the process moves to step S119, where the water temperature is detected using the water temperature sensor 30, and in step S120, the detected water temperature is compared with the set hot water temperature (40 ° C.). .
[0051]
When the detected water temperature is lower than the set hot water temperature as a result of the comparison in the subsequent step S120, the process moves to step S121 to drive the heater, and unlike the above case, the detected water temperature becomes the set hot water temperature. If the temperature is higher, the process proceeds to step S122 to turn off the heater.
[0052]
In the case of the toilet seat temperature control, the process moves to step S123, and the toilet seat temperature is detected using the temperature sensor 40. In step S124, the detected toilet seat temperature and the set toilet seat temperature (42 ° C.) Will be compared.
[0053]
If the detected toilet seat temperature is lower than the set toilet seat temperature, the process proceeds to step S126, in which power is supplied to the heating wire to drive the heating wire. If the temperature is higher than the set toilet seat temperature, the process proceeds to step S125, in which the hot-wire drive power supply is cut off to turn off the hot wire.
[0054]
That is, when the light at the place where the bidet is located (for example, a fluorescent light) is lit at midnight, it is determined that the user has performed to use the bidet, the power saving mode is immediately released, and the heater and the heater are quickly turned off. By operating the hot wire, control is performed so that the user can use the bidet comfortably without feeling cold.
[0055]
【The invention's effect】
According to the present invention described above, an illuminance is sensed using an illuminance sensor, and power saving is controlled according to the sensed illuminance level, thereby providing an effect of enabling optimal power saving.
[0056]
In particular, at midnight when almost no bidet is used, there is an advantage that required power can be reduced as much as possible by turning off both the heater and the heating wire.
